OF NEW YORK, N. Y.

IMPROVEMENT IN WINDING AND SETTING WATCHES.

Specification forming part of Letters Patent No. 4 7.4 [2, dated April25, R565.

To all whom it may concern:

Be it known that I, FREDERICK A. GILES,

parts of a-wateh. Fig. 2 is a side view of the.

same partly in section:

Similar letters of reference indicate corresponding parts in bothfigures.

The object of this invention is to provide for the winding and settingof watchesat the stern by means which are simpler and more durable thanthose heretofore employed for the purpose; and to this end it consistsin a novel system of gearing for this purpose, in which there are butone wheel. and two pinions inaddition to the ordinary wheel'work of the.watch, and by which 1 dispense with the ratchet-clutch, commonlyemployed, and

avoid using the minute-wheel and the breakage to which the teeth of thatwheel are liable in using it for setting the watch.

To enable others skilled in the art to construet and apply In yinvention I will proceed to describe it with reference to theaccompanying drawings.

. A is the ratchet-wheel connnonly employed upon the mainspring-arborfor the reception of the point of the click 9, which retains themainspring as fastas wound. Ois a wheel turning on a fixed pivot, n,screwed into one of the plates of the watch, having upon its periphery acircular series of teeth, a a, gearing with the teeth of theratchet-wheel A, and

npon its back or under side a circular series of contrat-e teeth, 0 c,to geariwith the teeth of an ordinary pinion, I), which is fitted toslide longitudinally upon a square portion of the winding arbor D. Thisarbor passes through the stem or pendant of the watch, in

which it is capable of being turned freely by applying the thumb andfinger to a knob, D, atits outer end, but it is-prevented from movinglongitudinally by a screw, j, entering a groove turned in it; o

The pinion b has rigidly attached to or formed in the same piece with ita contrate or crown pinion, d, which is of proper pitch to gear with theordinary cannon-pinion e of the watch. bi'ned and arranged relatively toeach other, to the contrate teeth 0 e of the wheel (J, and to thecannon-pinion, that when the pinion b is in gear with the said eontrateteeth 0 c the pinion d is out of gear with the cannon-pinion, and thatwhen (I is in gear with the cannon-pinion I) is out of gear with thecontrate teeth 0 c. A groove, '0', is turned in the pinion tor thereception of the forked end of a spring, f, which, when left free, holdsthe said pinion in gear with the contrate teeth a, and consequentlykeeps the pinion (I out of gear with the cannonpinion.

h is a longitudinally-sliding pin, one end of which protrudes throughone side of the case of the watch and the other end of which bearsagainst the springfin such manner that by pressing the said pin inwardwith the thumb toward the center of the watch, and so push the pinionsZ) and (I along the square portion of the winding-arbor, to which theyare fitted, in such manner as to bring d into gear with thecannon-pinion and I) out of gear with the contrate teeth 0 c.

When there is no pressure applied to the protruding end of the pin it,and the spring holds the pinion b in gear with the contra-te teeth 0 c,the turning of the winding-arbor causes the pinion I), which turns withit, to turn the wheel 0, the teeth (I a. of which turn the ratchet-wheelA and main spring-arbor, and so wind the watch without moving the hands,the pinion (I being out of gear with the cannon-pinion.

watch, the sliding pink is pushed inward far enough to cause the springfto carry the pin-i ion 1) out of gear from the contrate teeth 0 c andcarry the pinion cl into gear with the can non-pinion 0, so that byturning the windingarbor I) the hands may be turned without disturbingthe winding-train.

The teeth a a, on the periphery of the wheel 0, are represented as ofcurved or hook form, but they may be of ordinary spur form. Spurteethmay also be substituted for the ratchet.- teeth of the wheel A, as theclick g, Fig. 1,

The pinions (Z and 7) are so coinor finger it is made to push the saidspring When it is desired to set the hands of the which acts to hold themaiusp ing as fast as wound maybe so formed as to act on such teeth aswell as upon ratchet teeth;

What I claim as my invention, and desire to secure by Letters Patent,is-

The combination of the wheel. 0, having two series of teeth, aand '0,turning on a fixed pivot, n, thetwo pinions b d, inevablelengthwise uponthe arbor, the sprin g' f, and the slidin g pi'n'h, the whole arrangedand. applied in relation to the wheel A and the cannon-pinionsubstantially as herein specified.
